Specification of Letters Patent.

Patented Dec. 15,1914.

Application filed March 20. 1918. Serial No. 755,680.

To all whom it may concern:

Be it known that I, Once L. HEMMING, citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in' /Vire Straightening and Cutting-Off Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will'enable others skilled in the art to which it appertains to make and use the same.

My invention relates to wire straighten: ing and cutting-oft machines and it consists of an arrangement of mechanism for driving all of the rotatable parts of the machine from one driving shaft or single belt drive.

Referring to the drawings wherein the same figures of reference indicate like parts throughout the several views: Figure 1 represents an upper plan view of the head of a wire straightening and cutting off ma.- chine. and'outside mechanism. connected therewith. and a broken view'of the eXtension mechanism connected with the head: Fig. 2 is a side elevation looking in the direction of the arrow a. Fig. 1; and Fig. 3 is a front elevation and sectional view of the extension mechanism looking in the direction of arrow b. Fig. 2.

1 is the driving shaft iournaled in the brackets 2 and 3 proiecting from the base 4 of the machine. This shaft is further supported by the portion 5 of bracket 2, Figs. 1 and 2, secured to the bracket 6 by the screw 7 The rear end of the wire straightening arbor 8 is iournaled in the bracket 8. and its forward end in the machine head 9.

10 and 11 are tight and loose pulleys on the driving shaft. The forward end of this shaft carries the bevel pinion 12 to mesh with the bevel ring gear 13. secured to the inner face of the balance wheel 14, rotatably mounted on the cam shaft 15.

16 is a sprocket wheel secured to the hub 17 of the balance wheel which'is connected with the. sprocket wheel 18,'mounted on'the lower feed roll shaft 19, by the chain 20. The upper feed roll shaft 21 rotated from shaft 19 by gears 22 and 23 in the usual manner of machines of this class. The in ing shaft 1, and it rotates the straightening arbor 8 through the medium'of the belt, or silent chain 27, connecting said large pulley with the small pulley 28, of the straightening arbor.

It will thus be seen that all of the moving parts connected with the machine-head are driven from a single shaft. or what may be termed, a single belt drive, instead, as before mentioned, of having a separate belt to drive the straightening arbor. a separate belt for the balance wheel pullev 14, and a. separate belt for the feed roll shafts;

The balance wheel pulley, and the feed roll shafts are run continuouslv from the continuously running driving shaft 1. and when the incoming wire 29. Figs. 1 and 2. strikes the gage rod 30. located in the guide bar '31. said rod will actuate we l-known mechanism located at the forward evten sion of the machine. but not shown. which mechanism will actuate the pivo ed clutch lever 32. through the med um of the con necting wire 33 pulling in the direction in dicatcd bv the arrow 0. to elevate the urmer end 39f of said lever. and re ease the key 34. which kev will engage with the balance wheel 1 and temnorarilv bring the cam' shaft 15 into rotative enga ement with the a balance wheel and actuate the wire cuttingotl lever 35. mounted on the rock shaft 36;

At the completion of a re olut on'of the cam shaft. said shaft will be released and brought to a standstill. and the feed rolls and straightening arbor will be d iven independent of the cam shaft as beforerdescribed. The'clutch lever is iournaled on the sunport 37. mounted in the end of the boss 38. projecting from the machine-head.

All of the moving parts of the machine except the single belt driving feature. as represented by the driving shaft 1, and the means for connecting it with the rotatable parts of the machine, are old and well known.

Having thus described my invention, what I claim is The combination in. a machine of the '105 character described havinga straightening;

arbor, feed-r011 shafts, cam shaft, and its balance-Wheel pulley, of a driving shaft, means for rotating said shaft, a pulley on said shaft for, rotating the straighteiiing arbor, a bevel gear carried on the inner face 'of the balance-Wheel pulley, a bevel pinion ion the end of the driving shaft meshing H with the bevel gear, asprocket Wheel on'the hub of the balance-Wheel pulley and One 011 OTTO L.
